27 Claims. l

The invention relates to railway rolling stock and more particularly to the framing at the end of a vehicle including an upright end post and consists in the construction of the end post and its `assembly with the underframe.

The main object of the invention is to form an underframe and upright end post assembly well adapted to withstand longitudinal thrusts delivered to the post by lading as well as buing shocks delivered to the underframe, and the invention is intended particularly for use in cars used for transportation of pulp wood which is loaded up against the end post and the latter forms the sole means for retaining the load.

A feature of the invention is the anchoring of the post to the underframe so that forces tending to tilt the post longitudinally of the car will be adequately resisted.

More specifically, the invention comprises a pair of elements in the underframe which are spaced apart a substantial distance and an upright end post with its lower portion fitting between the underframe elements and anchored thereby by shims or weldments, there being opposing faces on said underframe elements and posts to resist shifting or tilting of the posts. The underframe elements may consist of spaced apart end sills or brackets or recesses in the longitudinal sills.

Figure 4 is a detailed vertical section taken on the line 4 4 of Figure l.

Figure 5 is a perspective of the lower portion of the end post.

Figures 6, 7, 9, and l2 are detailed sections corresponding to Figure 4, but illustrating different forms of the invention.

Figure 8 is a horizontal section taken upon the section line 8-8 of Figure 7.

Figure l0 is in part a top view of the structure shown in Figure 9 and in part a horizontal section taken on the line Ill-lll of Figure 9.

Figure ll is a similar top view and horizontal section, the section being taken on the line I I-I I of Figure 12.

The Vehicle underframe includes a center sill I of inverted U section, with flanges 2 at the lower edges of its legs, side sills 3 of Z section, transverse bolsters 4 of box section, an outer end sill 5 and an inner end sill 6 at each end of the car, spaced apart a substantial distance and forming the ends of a vertically opening pocket. Both sills are of channel section although the outer end sill has a box-like vertical section lat each end with an inner web 5a and the inner end sill has a depending angular reinforcement 1.

Near the end of the car the cross section of each side sill changes, the Vertical web being inclined, as indicated at 8 to merge with the end of inner end sill 6, land then is offset inwardly from the side of the car as indicated at 9 and then merges with the inner web 5a of the outer end sill to form with the adjacent portions of the end sills a recess facing away from the side of the car.

Upright end posts I0 and II, preferably two of each, are mounted upon end sills 5 and 6. Each post is of channel cross section and comprises a main web I2 extending longitudinally of the car with flanges I3 and I4 respectively projecting laterally from the front and rear edges of the web. The lower portion of the post is offset horizontally inwardly from the front and rear of the post to form downwardly facing shoulders I5 and I6 respectively, which rest upon end sills 5 and 6 respectively, and the lower end of the post is provided with an upwardly facing lip vor shear lug I'I opposing shoulder I6. A rib I8 extends diagonally from lip Il to shoulder I5. Each post may be tapered from its lower portion towards its upper end and web I2 may be apertured at l 9 to lighten the post.

When the post is applied to the underframe, it is inserted sideways into the space between the end sills land tilted to the upright position as shown in Figure 3 with its shoulders I'5 and I6 resting upon the sills, its lip I1 hooked under sill 6 and the offset flange portion Ida bearing against the front face of sill 6. One or more shims 2D are inserted between lip II and the bottom of sill 6. This structureavoids tilting of the post lengthwise of the car irrespective of the securing of the post to the top of the underframe.

Weldments 22 are deposited in the space between the front edge of post web I2 and web 5a of the outer end sill to take up any play between the post and the end sills and to secure the post to the underframe. Additional weldments 23, 24, 25, and 26 are deposited between the post and upwardly facing elements of the sills and contribute to the rigidity of the structure. The use of Weldments as described avoids the necessity of machining the opposing portions of the underframe and end posts to secure a tight fit but the securing eiect of a, machined t between these structural parts is attained.

The posts are braced against tilting transversely of the car and are tied together to form a more nearly unitary structure by an angle 3U the flanges of which are welded to the horizontal top faces and adjacent vertical faces of the posts.

Preferably the underframe and posts are constructed of cast steel and when so constructed as shown on the drawings provide for a strong end post construction and a strong, rigid connection between end posts and the underframe. The durability, strength, and corrosion resisting qualities of cast steel structures are usually much greater than for built-up structures, resulting in less maintenance and repair expense. The use of Weldments to provide a tting and securing of the lower portions of the posts to the end sills without machining and riveting the tted parts smplies the production of the parts and the assembly operations and lessens the cost of the completed structure.

The end posts are rigidly secured to the underframe and the structure resists forces applied in either longitudinal direction of the vehicle. The end posts cannot tilt outwardly of the car in a longitudinal vertical plane due to any forces tending to shift the lading, and they cannot tilt inwardly in the same plane due to sudden bufng forces or other forces which would tend to move the heavy end post in the opposite direction in which the force would move the heavy underframe casting.

Figure 6 illustrates another form of the invention in which the end sills 4l) and 42 are of box section. Both upright walls of sill 4Q and the rear wall of sill 42 are substantially vertical but the front wall 43 of sill 42 is inclined rearwardly and downwardly. The lower portion of end post M has a substantial vertical front ange 45 opposing the inner wall 4i of the outer end sill and has an inclined rear flange 46 opposing wall 43 of the inner end sill.

The side post may be disposed parallel to the side of the underframe and slidlaterally into the laterally open pocket in the underframe. The `center post may be disposed at an angle to the end sills and lowered into the spacebetween the end sills and then twisted horizontally to bring it into the assembled position shown. Shims 41 may be inserted between wall 4l and flange 45 to thrust iiange 46 against wall 43. Downwardly facing shoulders on each end post rest upon the end sills. Weldments 49 are applied to the corners between each post and the end sills.

Figures '7 and 8 illustrate a structure in which sills 50 and 5| are of box section with their inner walls 52 and 53, respectively, disposed vertically. The lower portion of each post 54 has lips or shear lugs 55 and 56 underlying sills 5U and 5I, respectively. shims l are inserted between lips 55, 56 and the bottoms of the end sills. Shims 58 are inserted between the rear vertical lower portion of each post and the opposing wall 53 of the inner end sill. Weldments 59 are applied to hold the shims and posts in position, but the Weldments are not relied upon to resist forces tending to tilt the end post in a longitudinal vertical plane, either inwardly or outwardly of the underframe.

Figures 9 and 10 illustrate another form of the invention in which the end sill 60 is of box section, but in pla-ce of the inner sills shown in the other arrangements, there are brackets 6l and 62 extending inwardly and outwardly from the underframe side sill and center sill respectively and. spaced from the end sill. The lower portions of posts 83 are received between the opposing faces of end sills 60 and brackets 6|, B2. Shims 64 are inserted (between end sills 65 and the opposing vertical faces of posts 63, and weldments 65 secure all of the parts together. Forces tending to tilt the posts lengthwise of the underframe are resisted by the opposing elements of the posts and underframe independently of the Weldments.

Figures 11 and l2 show another arrangement for fitting the end posts to the underframe structure. In this arrangement the end sill 'l0 is of box section with its inner wall ll inclined rearwardly and downwardly. Brackets l2 and 73 correspond to the brackets shown in Figure 10, but their forward walls are inclined downwardly and forwardly. The front and rear flanges on the post 'I4 converge downwardly by providing clearance between the downwardly facing shoulders l5 on each post and the upper face of the adjacent part of the underframe. The post may be lowered into the underframe until there is contact between the front and rear portions of the posts and the opposing elements of the underframe, thus eliminating the use of shims. Any space between shoulders 15 and the underframe may be lled with shims or with weld- -ments 16.

In all of the arrangements the t between the posts and the underframe is made without requiring any machining of either casting adjacent to the nt. All play at the t is taken up by shims or Weldments or by the taper of the opposing surfaces. troductory portion of this speciiication are attained by any of these structures.

The details of the device may be varied otherwise than as shown without departing from the spirit of the invention and the exclusive use of those modifications coming within the scope of the claims is contemplated.
